The Bigsby was the first successful design of what is now called a
whammy bar or tremolo arm, although vibrato is the technically correct
term for the musical effect it produces. In standard usage, tremolo is a
rapid fluctuation of the volume of a note, while vibrato is a
fluctuation in pitch. The origin of this nonstandard usage of the term
by electric guitarists is attributed to Leo Fender, who also used the
term “vibrato” to refer to what is really a tremolo effect.

I've agonized what to put on two Strats and a Junior I've built. But in the end i just left them blank. Doesn't look as odd as I thought and gives them an air of mystery. I get people asking about them and wanting a go which is nice:)

I umm'd and ahh'd about a decal for my 'caster for ages but decided everything i tried looked out of place or the wording was just meaningless or daft, went with no decal in the end, I ththi it looks better tbh.
